If, thanks to my EGR valve, I have to crank the starter for nearly 10 secs before it'll start and the 'Car with the spanner' comes on it'll tick over, and drive very nicely indeed!
If however the engine starts instantly on the first turn of the starter the engine idles smoothly for 5 or 6 seconds before it dies. Repeating this even if I restart unless I rev continuously and it drives with lack of power which comes and goes in waves. I have 5 or 6 seconds of power followed by 2 or 3 of power loss this cycle repeats predictively .
Believe it or not my dodgy EGR valve is currently doing me a favour!!
It's been on diagnostics and all sensors are showing ok. Codes 400 (egr) 300 (mis detected) 304 (mis cylider4). is all thats displayng. All codes were cleared and the same ones came back shortly after, with no others.
I had a timing belt and head gasket fitted 5 months ago and I've only done about 700 miles since. This problem has come on gradualy since. Could this be an incorrectly fitted timing belt? Could it have slipped a tooth or two? Would a dodgy head gasket cause this (hydro lock)? Also does the fact that it'll go ok when it's in limp home mode point me in any direction? I'm not taking it back to the guy who did the work because he's insisting my piston rings have gone!!
